Longfellow Bridge Detour July 20: Map

As the Longfellow Bridge rehabilitation major construction begins, the bridge will be closed for vehicular travel in the Cambridge-bound direction.

Effective July 20, 2013, one lane of traffic will carry vehicles into Boston (using the current Cambridge-bound lane) and Cambridge-bound traffic will be detoured using a signed route from Charles Circle to Land Boulevard using Leverett Circle and Monsignor O’Brien Highway. The detour route is shown below.

The three and a half year project to rehabilitate the Longfellow Bridge will require a closure of the bridge to traffic in the Cambridge-bound direction for the duration of the project.

One vehicle travel lane to Boston, MBTA Red Line service inbound and outbound, emergency response, and bicycle and pedestrian access will be maintained throughout construction.

The implementation of the detour is weather dependent. If heavy rains are predicted, the detour will be delayed one week to ensure the new configuration is put in place during a weekend.

The Longfellow Bridge Rehabilitation is a $255.5 million project to restore the historic, iconic bridge. The project is funded through the Patrick Administration’s Accelerated Bridge Program to repair and replace structurally deficient bridges around the Commonwealth.

One thought on “Longfellow Bridge Detour July 20: Map”

Please improve pedestrian crossing from Charles MGH Redline MBTA to Charles Street (toward Beacon, away from Mass General Hospital) crossing of first leg of Cambridge Street inbound. Driver's coming off Storrow drive and bridge don't see the condition of the walk/do not walk signal and either stop when peds have do not walk or go through crosswalk when peds have walk. Was bad prior to Longfellow bridge rehab traffic pattern, but is worse now. Please address and improve so as to avoid accidents and near accidents! (20130916)
